Abstract (en)
[origin: EP1757550A2] A method and apparatus are provided, for handling the backing film in a fiber placement process, by winding-up the backing film, into a roll, as the backing film (102a,102b) is separated from a fiber tow (114a-b). The backing film is wound-up in such a manner that it can be fed back out to rejoin the tow, should it be necessary to rewind a portion of the tow during the fiber placement process. The backing film may be wound onto a paper or cardboard core for ease of removal and handling.
